web/main.py wires the address-mode endpoint at /, dispatches to the
Burr FSM, and returns the reconciled paragraph + per-step trace as
JSON for the front-end to render. /compare and /register/{class}
routes are stubbed for the next slot.
The static UI follows NYC Planning Labs' civic-assessment idiom
(ZoLa, Capital Planning Explorer): clean two-column layout, IBM
Plex Sans throughout, MapLibre for the map, vanilla JS event flow
with no framework. NYCO design-system CSS + fonts ship as a vendor
drop so the build stays Node-free.
